  Not easilly, you will have to do some hacking.
First this won't work purely at a SAX level, if you
build the tree it should be doable by hacking the 
start and end Document callbacks in the SAX parser to
link the preparsed DTD and remove it at the end. You
will also probably want entity replacemnt to be activated to
avoid stale links to the DTD from the tree.
  Very hackish but doable IMHO.
